Popularized by Robert Louis Stevenson’s Treasure Island, pieces of eight spread throughout the Americas through Caribbean trade, Asia, and exportation of wealth to Spain and Europe. Treasure ships were targets for pirates and victims of storms. Sunken treasure discoveries yield these types of coins. The history timeline of the Spanish conquest of Central and South America, silver mining, and mint establishment will be traced. The making of cob and milled coins of shield, pillar, and bust types took place over a period of 250 years. They were accepted as legal US tender until 1857!
